Info; Supplementary Identification Form

[Qwerty20]

hi!
I'm going to Canada this week to apply for my PR card. I forgot to request for the Supplementary Identification Form [IMM 5455], and Fees Receipt [IMM 5401], I did it today actually. So, Could anyone let me know, if I get everything else ready ( notarize, photos etc.) and hand it over to my friend, will he be able to fill out those forms and mail them for me.
OR
Do I have to get them notarize too !!!
What is this form actually, as you cannot download it from the CIC website.

Please do reply as soon as possible...
Thanks in advance.

One of the form is to pay the Fees to process your application, and on the other you affix one of your photographs and sign it. So you will need this form to sign it. Your application cannot be mailed till this form is signed.
